Abstract

This study aims to determine and compare the accuracy of Total Suspended Solids (TSS) estimates using Sentinel-2B and Landsat 8 satellite imagery in the Suwung estuary, Denpasar city, Bali. The TSS measurements in the laboratory were carried out on 20 samples for Sentinel-2B (LabS) and 20 samples for Landsat 8 (LabL) which were taken at the same coordinates. Regression and correlation methods are used to validate TSS estimates against laboratory TSS. Accuracy tests to determine the level of estimation error use root mean square error (RMSE), mean absolute error (MAE), and mean relative error (MRE). Comparison of estimation accuracy is determined by differences in error rate calculation results. The results of regression analysis and accuracy tests for paired samples show a very strong correlation, both in pair 1 (LabS with Sentinel-2B) namely r=0.9484 and in pair 2 (LabL with Landsat 8) it is r=0.8910, and the error rate for pair 1 is smaller than pair 2. The implications of these results show that the accuracy of the TSS estimation of the Laili algorithm using Sentinel-2B is better than Landsat 8.
